ABC entertainment president Paul Lee conceded to reporters Sunday at the Television Critics Assoc. press tour in Beverly Hills that Revenge “stumbled a bit” in its mythology-heavy second season, adding that new showrunner Sunil Nayar (who replaced series creator Mike Kelley) will “bring to us a slightly less complicated” storyline in Season 3. “The first episode back is a fantastic episode starting with a magnificent hook.”

NASHVILLE| Lee defended Nashville‘s super-soapy Season 1 car crash climax, calling the twist a “sweet cliffhanger… There’s an impending doom that leads you toward the car crash that is very Nashville.” In Season 2, Connie Britton’s Rayna will “really drive plot,” Lee added. “That particular rivalry with Connie and Hayden[‘s characters] is coming to a head. We’ve only seen a couple of outlines and a script, but we’re really happy with it.”

ONCE UPON A TIME IN WONDERLAND | On the decision to launch the Once spin-off in the fall as opposed to at midseason as a bridge between the first and second half of Once Season 3, “We just fell in love with it. We were looking to build a real block on Thursday of empowered women… This is Alice like you’ve never seen Alice before. She’s a truly kickass Alice.”

DANCING WITH THE STARS| On Maksim Chmerkovskiy returning for the next cycle, “Maks is part of the family; he may well be back [next season].” As for how the competition series will manage with no more results show, Lee would only say that Monday’s two-hour telecasts would “build to a climax at the end” and still involve some combo of judge and viewer votes.

HAPPY ENDINGS | Lee called the beloved comedy’s untimely cancellation “very upsetting,” but noted that the show failed to “attract an audience on its own” after it moved out of the post-Modern Family slot. “We never found in the places that we put it [that] we could [bring] an audience to it. We couldn’t find its sea legs away from a strong lead-in, so that’s how we ended up on that decision.”

GREY’S ANATOMY | The long-running medical soap is not heading into its final season, Lee maintained. “[Shonda Rhimes] is planning a number of [season’s] out… We would like to see it on the network for many years to come.” Lee declined to comment on the future of original castmembers like Ellen Pompeo and Patrick Dempsey (whose contract expire in May), saying, “If I commented on who is coming in and out, I think Shonda would yell at me.”

CASTLE | When asked about Nathan Fillion’s recent unauthorized “day off” from Castle in the midst of a contract squabble with ABC, Lee deflected, “Nathan and Stana [Katic] are fantastic actors. We feel super-optimistic” about Castle‘s future.

SCHEDULING | ABC detailed its split-season schedule for its heavy hitter dramas, revealing that Nashville will return from its winter break on Feb. 26, Grey’s Anatomy and Scandal will resume their runs Feb. 27, and Once Upon a Time and Revenge will come back March 9 — with all of the above finishing their seasons with few or no repeats. (Lee told TVLine that midseason programs such as Tricia Helfer’s Killer Women will fill those midseason gaps.) The new reality series The Quest, meanwhile, will at least temporarily replace Once Upon a Time in Wonderland (Thursdays at 8) starting Jan. 2, while Resurrection will take over for Betrayal (Sundays at 10) on March 9.
